- def apply[T <: Data](functionName: String, ret: => T, inputNames: Option[Seq[String]] = None, outputName: Option[String] = None)(clock: Clock, enable: Bool, data: Data*): T
Creates an intrinsic that calls non-void DPI function at its clock posedge.
Creates an intrinsic that calls non-void DPI function at its clock posedge. The result values behave like registers and the DPI function is used as a state transfer function of them.
enable
operand is used to conditionally call the DPI since DPI call could be quite more expensive than native constructs.When an
enable
is false, it means the state transfer function is not called. Hence their values will not be modified in that clock.Please refer https://github.com/llvm/circt/blob/main/docs/Dialects/FIRRTL/FIRRTLIntrinsics.md#dpi-intrinsic-abi for DPI function ABI.
val a = RawClockedNonVoidFunctionCall("dpi_func_foo", UInt(1.W))(clock, enable, b, c)

This is the documentation for Chisel.
Package structure
The chisel3 package presents the public API of Chisel. It contains the concrete core types
UInt
,SInt
,Bool
,Clock
, andReg
, the abstract typesBits
,Aggregate
, andData
, and the aggregate typesBundle
andVec
.The Chisel package is a compatibility layer that attempts to provide chisel2 compatibility in chisel3.
Utility objects and methods are found in the
util
package.The
testers
package defines the basic interface for chisel testers.
